Alumina Ceramic Lining Hardness Test Way



High density alumina ceramic linings and abrasion resistant tiles prevent destructive wear in conveying, processing,and storage equipment. it is made from high purity, fine grain, alpha aluminum oxide, a material almost diamond hard.which is widely used in indutries of mining ,primary steel,fire power plant,cement,port etc 

Normal alumina ceramics property inclues hardness,density,water absorption,flexural strength, fracture toughness,and hardness is one of property which measure the alumina ceramic lining quality.normally the harder the ceramic liner is, better wear resistance property the alumina  ceramic is.we often indicate the hardness by Moh's harndess, Vickers hardness and Rockwell hardness. 

  1: Moh's hardness is by scratch method ,tapered diamond pin scratch the surface of mineral
stone, the stone tools includes talc,gypsum, calcite,fluorite, apatite,feldspar,quartz,topaz,corundum,diamond, these stone materials represent 10 grade hardness.

  2: Vickers hardness : it is calculated by counting the indentation length within a certain time .

  3: Rockwell hardness : size 1.59mm/3.18mm steel ball drop down into the material surface with certain load. then the rockwell hardness is calculated with the depth of indentation 

Pingxiang chemshun ceramics co.ltd （www.chemshun.com）is professional alumina ceramic lining manufacturer ,we have independent wear ceramic liner study and test lab with advanced machines. every batch of ceramic products goods will be tested in order to supply high quality abrasion resistant ceramic products.

What are the characteristics of abrasion-resistant ceramic tiles?

What are the characteristics of abrasion-resistant ceramic tiles?  Abrasion-resistant ceramic tiles are widely used in many projects, in the pit furnace is also built with a wear-resistant ceramic tiles, wear-resistant ceramic tiles not only to fire resistance, high temperature requirements, but also to wear requirements, Introduce the impact of wear-resistant ceramic tile wear-resistant factors which have! Abrasion resistance of  abrasion-resistant ceramic tiles  depends on the composition and structure of wear-resistant ceramic tiles. When the abrasion-resistant ceramic tiles are composed of dense polycrystals composed of single crystals, the wear resistance depends on the hardness of the mineral crystals. High hardness, high wear resistance of the material. When the mineral crystals are non-isotropic, the grain size is small and the wear resistance of the material is high. When the material from the multi-phase composition, the wear resistance of the material ...

What are interlocking wear-resistant ceramic tile liner ?

图片
  The shape of ordinary wear-resistant ceramic tiles is a square sheet structure, and they are arranged in rows and columns. There are linear seams between the rows and columns of wear-resistant ceramic sheets. The linear seams along the direction of fluid flow are A smooth fluid scouring gap is formed.      In addition to the normal wear of the fluid on the surface of the wear-resistant ceramic sheet, the erosion gap becomes a breakthrough door for the fluid to wear the side of the ceramic sheet. Under the long-term erosion of the fluid, the seam will gradually widen and the degree of wear will become more and more serious. , the change of connection affects the service life of the wear-resistant ceramic sheet, which in turn affects the protection effect of the anti-wear parts. After this kind of wear-resistant ceramic sheets are pasted, the adjacent ceramic sheets do not have an interlocking effect with each other. The pasting is not strong during installation...

How to improve the wear resistance of Al2O3 ceramics

图片
Al2O3  wear resistant ceramics  as lining of mill and grinding medium, in the construction of sanitary ceramics and other industries has become more and more widely applied. Use material of Al2O3 content is between 90% ~ 99% commonly, in order to produce high density, good wearability ceramic body, must have a suitable raw material performance, forming method can obtain high green density and must have the appropriate sintering temperature and holding time, only the three elements meet the requirements at the same time, in order to achieve this purpose. Chemshun company has been working hard to develop, research, innovation design is most suitable for customer requirements of high alumina  wear resistant ceramic  products.
